Hi,

I just want to know the best way to configure wireless access points, i may have to configure 4 or maybe 5 in the same building.

The internet is setup through the phoneline - adsl

Heres my understanding...

-The ADSL router acts as a DHCP server ...
-then access points are added to the router with dchp off..
-So access point A is connected to the router...
-then the other access point B is connected to access point A...
-then access point C goes to B and finally D to C...


my questions are,

is this the correct way to configure this?
Do all of these access points have to have the same SSID?
And which ip range should i choose if the adsl router is currently set at currently set as 192.168.1.254


Ive attached an image to show you what i mean...



Thanks for your time,


Kind Regards,

jg623

Hi,
Yes they should all have the same ssid but put them on non overlapping channels. All device will be on the 192.168.1 network but dhcp should take care of that for you i think.

 Azn jg623,
here is a few tips you might use........................

1: Avoid placing access points near structural metal

When setting up a new wireless access point, you should install it in a location that will be unlikely to cause radio interference. I once had someone contact me because their wireless network was not working correctly. When I asked them to show me the access point, they led me into the warehouse where the access point sat on top of a steel beam just beneath a metal roof. The surrounding metal was interfering with the signal. Moving the access point took care of the problem. Since that time, I have always advised clients not to place access points in close proximity to structural metal.

2: Use Power over Ethernet when necessary

People like to place wireless access points on or near the ceiling in an effort to help wireless  achieve the best possible range. But it can be difficult to get power to the access point. Rather than rely on extension cords (as I have occasionally seen done), consider using Power over Ethernet (PoE). PoE provides the access point with power over unused wires within an Ethernet cable. Special PoE modules at each end of the cable ensure that networking hardware is not exposed to the electricity the cable is carrying.

3: Reset the access point password immediately

The first thing you should do when setting up any new wireless access point is reset the access point’s internal password. Otherwise, the access point’s configuration interface will be accessible to anyone who knows how to look up the default password on the Internet.

4: Take advantage of built-in security features

Even the cheapest wireless access points come loaded with numerous security features. For example, most access points will allow you to restrict network access by MAC address. Some wireless access points also contain alerting mechanisms that can fire off an email message if someone repeatedly attempts to connect to your network using an incorrect pass phrase. Be sure you check out the security features your wireless access point offers and enable the ones that seem beneficial.

5: Restrict the number of concurrent connections

A suggestion I like to add to the security of the access point is restrict the number of concurant connections. You will have an idea just how many devices will be accessing it at any one time.. restricting the connections can help stop or at least alert you to some unauthorized access. In a home enviroment that can keep your neighbors off your wireless even if they did manage to learn your access code.

Hope some of those suggestions help you out and other members take care

Thanks for the tips.

I have a few more questions regarding the initial set up.

Ive managed to set up 3 wireless routers, but they are all on different networks as ive found dchp quite tricky.

router #1 is the adsl router (192.168.1.254)
router #2 is connected to router #1 via a 30 metre cat5e connection (192.168.0.1)
router #3 is connected to router #2 via a 20 metre cat5e connection (10.10.10.1)

all of these work fine as i had trouble configuring dhcp...

are these the steps below in order to get it to run on one network instead of 3?
Give router #2 a static ip via the LAN setup in the configuration lets say 192.168.1.253 (one less than the adsl) and turn DHCP off and change the SSID to the same as #1
then the same with #2 happens with #3, giving the static ip of 192.168.1.252

or should the other access points/routers be configured via the dhcp address .. 192.168.1.101 (#1), - .102(#2), - .103 (#3)

I'm just slightly confused.

Thanks for all your help.

  Azn jg623,
just a few questions, so A is the one connected to the router, right? What is the default gateway for the router? what is the default gateway of A given by DHCP?  I'm assuming that none of the other routers have a direct access to the Internet (phone line), am I correct?

Please reply the info and we can better understand the situation and continue helping you. Take care

Yes A is the one connected to the router. I'll have to check the default gateway of both the ADSL router and the Router A, as i wont be there to check it out for a few days.

no, none of the routers have a direct access.

the ADSL router is a bt business hub, the router A is a TP Link and the router B is a netgear.

I just picked up ones that were spare, of course i wont have it set like this when its up and running. Although for testing purposes i was trying to see how far i could get with the 2 other routers. Just so i know where to put switches in for the 3rd floor and where to put POE routers.. if needed

I'll let you know how i get on when im there.

Could you pm me any chat messengers you use? and what time is best to contact you..

Your help is greatly appreciated!

Wink

 Azn jg623,
I don't use chat programs much really and a good time to catch up difficult however I have given you a link to a post I did a few weeks ago that should be of a considerable help to you, good luck jg623 and report back when your sorted. Take care glad to help out

Hi,

I think i have a slight problem. Basically ive set up all the routers and they work fine. However as i have 1 router and 3 access points i dont know how to configure the channels, i know of 1,6,11 . what should i set the last access point?

another point ,

I have set up another router in my friends house, without using a homeplug or cabling, is it possible to make a wireless repeater/bridge ? I tried the basic steps:

making the routers the same SSID
used WEP encryption (for repeating, as its the only one you can use) and set the same on both
set the master device as the one in the living room and i keyed in the mac address,
used basically the same settings on the repeater , apart from selecting it as a repeater and not a base device.

I cant seem to get it to work, i wasnt sure if this was possible in the first place but it seems logical..

Thanks for your help

Lol, looks like Brian didnt have his coffee this morning. I did create this topic !  :Smiley

Nevermind the wireless bridge i got that sorted. Im still not sure which channels to use for a router and 3 access points.. 2 access points can see the router, but the router can see the last access point, which means i need to pick 4 different, non overlapping channels.

Any help is appreciated

Thanks
